Description

Technical Field

[0002] In the field of seed and seedling cultivation, heating and heat preservation equipment plays an extremely critical role. In different stages of actual cultivation, the temperature required for seeds and seedlings in the cultivation process varies significantly.

[0003] However, existing heating and heat preservation equipment lacks the ability to perceive and respond to such changes. It can only heat according to a preset fixed heating range, and thus cannot ensure that all seeds and seedlings are evenly heated. Local overheating or overcooling is prone to occur, which seriously affects the quality of seed seedling cultivation and may even lead to cultivation failure. For example, in some vegetable seedling cultivation bases, the uneven heating of traditional equipment has caused inconsistent and uneven growth rates of seedlings, affecting subsequent transplanting and planting plans. In addition, uneven heating may also cause the breeding of pests and diseases, because an unstable temperature environment is conducive to the reproduction of pathogens and pests.

[0034] like Figure 1-7The heating and heat preservation equipment for seed and seedling cultivation shown in the figure, when in use: the seeds to be cultivated are evenly distributed on the breathable support cloth 202 on the top of the placement net 201; the controller 103 controls the operation of the fan 5 and the resistance heating tube 6 at each position according to the temperature information sensed by the temperature sensor 203, and the operation of the fan 5 will evacuate the heat heated by the resistance heating tube 6 upward to the seeds on the breathable support cloth 202, thereby heating and heat preservation of the seeds in the seedling cultivation process; at the same time, a heat guide adjustment mechanism is provided, so that the output shaft of the first motor 703 in the heat guide adjustment mechanism can be used to drive the drive gear 704 to rotate forward and reverse, and the drive gear 704 rotates When the horizontal sliding column 700 is moved left and right, it also drives the linkage pin 706 to move and makes the linkage pin 706 slide and cooperate with the linkage groove 801 on the heat guide plate 8, so that the heat guide plate 8 can swing left and right based on the rotating shaft 802.
